*This percentage is based on a combination of two things:
each player's percentage of Points Added in his team's games, and his percentage
of Points Added when he's actually in the game. The former
is roughly twice as important as the latter (what a player contributes
is more important than how long it takes for him to contribute it, although
both are important), so the weighted percentage is based on a 2/3-1/3 split.
(One could quibble about whether this should perhaps be a 3/4-1/4 or 3/5-2/5
split instead, but any split in this range would leave the players' rankings
essentially intact, and the 2/3-1/3 appears to be the most accurate based
on AndersonSports's analysis.)
Why look at percentage of Points Added? This is the most
accurate way to rank a player's value, because it allows for the pace of
the game to be factored in. It is much easier to contribute Points
Added in games played at the Dallas Maverick's pace (97.3 Points Added/G)
than at the Miami Heat's pace (74.0 Points Added/G). Percentage-wise,
though, it's equally difficult. This allows for fair comparisons
among players whose teams play different styles.
*Points per shot measures a players' scoring efficiency.
It shows how many points a player scores on average when he shoots (with
two free throws counting as one shot).
